Hund’s Rule, Interorbital Hybridization, and High-$T_c$ Superconductivity in the Bilayer Nickelate

Posted by dbos UCAS

Kavli Affiliate: Gang Su | First 5 Authors: Xing-Zhou Qu, Dai-Wei Qu, Xin-Wei Yi, Wei Li, Gang Su | Summary: Understanding the pairing mechanism in bilayer nickelate superconductors constitutes a fascinating quest. Using density matrix renormalization group for $T=0$ and thermal tensor networks for $T>0$ properties, along with density functional theory calculations, we investigate the […]

Roles of Hund’s Rule and Hybridization in the Two-orbital Model for High-$T_c$ Superconductivity in the Bilayer Nickelate

Posted by dbos UCAS

Kavli Affiliate: Gang Su | First 5 Authors: Xing-Zhou Qu, Dai-Wei Qu, Wei Li, Gang Su, | Summary: The intriguing interplay between the two $e_g$ orbitals in the high-$T_c$ nickelate superconductor La$_3$Ni$_2$O$_7$ is studied via the density matrix renormalization group (DMRG) and finite-$T$ thermal tensor-network calculations. We consider a bilayer $t$-$J$ model that incorporates both […]

Quantum Gravity Effects on Fermionic Dark Matter and Gravitational Waves

Posted by dbos Tokyo

Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Stephen F. King, Rishav Roshan, Xin Wang, Graham White, Masahito Yamazaki | Summary: We explore the phenomenological consequences of breaking discrete global symmetries in quantum gravity (QG). We extend a previous scenario where discrete global symmetries are responsible for scalar dark matter (DM) and domain walls (DWs), […]

Third harmonic generation enhancement and wavefront control using a local high-Q metasurface

Posted by dbos Caltech

Kavli Affiliate: Harry A. Atwater | First 5 Authors: Claudio U. Hail, Lior Michaeli, Harry A. Atwater, , | Summary: High quality factor optical nanostructures provide great opportunity to enhance nonlinear optical processes such as third harmonic generation. However, the field enhancement in these high quality factor structures is typically accompanied by optical mode nonlocality. […]
